From the Youtube post:
Fr. William Casey gives a talk for a retreat June 17 – 19 at the Mother of the Redeemer Retreat Center called “In Our Lord’s own Words: The Divine Mercy” based on the words of Our Lord to St. Faustina that he compiled from her Diary and recorded on a set of CDs he recently published. This talk is titled “God Have Mercy on Us.” In the face of so much collapse of faith and morals in recent decades, Father exhorts us to ask for God’s Mercy and to lovingly and respectfully give people the message of the Gospel even when it may not be pleasant or convenient to do so. This is because the greatest mercy you can show people is to be concerned with their eternal salvation. We should relight the flame of faith by becoming saints. More notes below.
